To @ZZ whom t may concern: chine, on which are two pulleys, as shown, Be it known that I, HENRY J. COLBURN, a one of which vmay receive'a belt from some citizen of the United States, residing at Tosuitable motor, and a belt may be applied to ledo, in the countyof Lucas and State of Ohio, the second pulley connecting the same with 55 5 have invented certain new and useful Ima pulley on a horizontal moldactuating shaft provements in Glass-Blowing Machines, of 6 near. the lower end of the machine over which the following is a specification, refersaid mold-wetting tank 3.

Said two mold-Sections are supported on the Referring to the drawings, 2 2 indicate the mold-section table 63, Fig. lO, andtheyhave end uprights, 4 the Atop plate, and 52 the vera sliding movement thereon engaging `the 95 45 tical intermediate posts of the frame of the dovetail rib thereon, whereby the sections machine. A mold-wetting tank 3, secured are moved toward and from each other in rmly between the said end uprights 2 at the closing and opening the mold. Said moldlo-.ver ends thereof, constitutes substantially section table 63 has integral with its under the base of the machine. side the circular projection 16 and the bevelloo 5o A main driving-shaft 7 is supported in suitgear 10. Ashaft-passage 7S is formed through able bearings ou the upper part of the mathe center of said-gear l0 and the Said table.

A shaft 14 (see Fig. 5) extends from the inside of the bottom of the mold through the same and through the table 63 and through the'moid-supporting case 9,as shown in said last-named figure. Said shaft 14 has a circular plate or head 17 thereon, (see Fig. 9,) which constitutes the bottom proper of the mold. The said mold-supporting case (see Fig. 14) has a circular recess 79 in its upper side, which receives therein said circular projection 16 on the table 63. Referring to Fig. 5, a gear 11 there shown is fixed on said shaft 14 within the case 9. The gear 10 there seen is that shown as a part ofv the said table 63, and the gear 13 in said case, which engages said gears 10 and 11, is fixed on the end of the shaft 24, which shaft extends through the arm 82 of said case, and on the outer end of said shaft is fixed the gear 23, to which rotary motion is given by the gear 22, Figs. 1, 4, and 6. Said gear 22 is fixed on one end of a clutch-sleeve 21, which is hung firmly on said shaft 6 and is caused to rotate with and by said shaft or t-o remain at rest thereon by the action of the below-described devices. A clutch-collar 18 has a spline connection with said shaft 6, but is free to slide thereon for engagement with and movement from said clutch-sleeve 21, whereby the latter is rotated and stopped. Said clutch-collar 18 is engaged by a fork 20, carried on a fiexible shipping-lever 19, Figs. 4 and 6, which lever is pivotally hung by one end to a sleeve 81 on the part-supporting shaft 59 and extends from thence over said collar, as shown. A spring 25, secured by one end to said sleeve 81 and bythe opposite end to said lever, acts to swing the fork-bearing end thereof and said clutch-collar away from the serrated end of said clutch-sleeve 21 and stop the rotary motion of the latter. Alat-ch-spring 26, Fig. 6, is supported on the upper part of the yoke 80, and its free end extends under the end of the said lever and engages the latter, thereby holding said lever and clutch-collar in the position shown in said last-named figure. On the stud on which said spring 26 is held is placed a ratchet-wheel 28, Figs. 5 and 6, and a pin 27 on said sleeve 21 strikes a tooth of said ratchet-wheel at the completion of each full rotation thereof. Consequently, there being twenty-five teeth on said ratchet-wheel, the latter will be caused to rotate once to every twenty-five rotations of said shaft 6 and the sliding clutch-collar carried thereon. The ratchet 28 is interchangeable for others of different numbers of teeth, whereby the duration of the rotary movement of the molds 60 may be varied, according to the varying thickness of the blown articles. An upstanding arm-bearing post 3'.) is rigidly secured on said lever 19, having an arm thereon extending toward the adjoining face of said ratchet-wheel 28, on which is a horizontallyprojecting pin 29. The underside of said arm on the post 30 is inclined or cam-shaped, as indicatedin Fig. 7, to the end that when said pin 29 is carried against the under side ot' said arm the post 30 and the end of said lever 19, to which it .is attached, are lifted out of engagement with said spring 26, and said spring 25 then acts to swing the free end of said lever and the clutch-collar 18 so that the latter isdisengaged from the clutch-sleevo 2l, as described, and causing the movements of the latterand parts driven thereby to cease at the end of twenty-five revolutions of said shaft 6. Said last-named shaft has its bearings on and is supported to rotate by the brackets 5, which are bolted to the tank 3, and indirectly by the boxes 80, which are also bolted to said tank and in which said elu tch-sleeve 21 is held to rotate. Each mold of the series comprising the-herein-described system is operated for wetting the same in water contained in said tank 3thereunder by a rock-shaft. Said rock-shafts for the three molds and accessories illustrated in Fig. 1 are indicated by 40, 41, and 42 and are suitably supported on the rear side of said tank or other convenient place. Each of said shafts is provided with a hand-lever 37, 38, or 39, the free end of each lever swinging at the side of a curved latch-bar 72, Fig. 2, and having aspring-latch thereon for engagement with a notch in said bar at each extremity of said bar, as shown. Referring now to the mold at the right in Fig. l and to said rock-shaft 40, the latter has an upright arm 74, Figs. 1 and 5, fixed thereon, to which one end of a connecting rod or bar 75 is connected, Figs. 4 and 5, and the opposite'end of said rod is connected to an arm 8 on one of the boxes 80 on one of the arms 15 on said mold-supporting case 9. Thus when said lever 37 is swung from the position shown in Fig. 2 in full lines to the dotted-line position there shown the mold-supporting case and mold will be swung downwardly to the position indicated in dotted lines in Fig. 5, whereby the mold is suitably wetted, after which it is again swung upwardly to its operative position. The mold is opened or its two sections are moved one away from the other, as shown in Fig. 9, by sliding each section on said table 63, Fig. 10, by the following-described means: On said shaft 59 (which supports certain parts) are secured two sleeves 69 69, and to each of said sleeves a lever is pivoted, the free ends of the two levers being bent to hook form, each for engagement in the said semicircnlar groove 61 in the base of the moldsections 60. Between said sleeves 69 on shaft 59 an arm 65 is rigidly secured, on the end of which is secu red a revoluble disk 66, on which are pivoted two connecting-rods 71, which rods by their outer ends engage said two levers 70 70. (See Figs. 8 and 9.) On the border of said disk 66 is aslotted arm 67. A rod 33,'

pivoted by its lower end to a foot-treadle 31, extends vertically near said disk 66 and carries a pin 68, which engages in the slot of said arm 67, so that when said rod is moved upward or downward the disk 66 is rotated IOO IIO

more or less and the said levers are swung, thereby imparting said opening and closing movements to said mold-sections. l

At the top of the machine directly over each mold is located a hollow shaft 44, Figs. l, 2, and 3, arranged to rotate in suitable bearings on a standard 43 and to have a vertical movement in said bearin gs. A grooved pulley 46 is placed on said shaft between the bearings thereof, having a spline connection with said shaft, whereby said vertical movements are permitted. A lever 34, hung on said standard 43, has one end engaging with said shaft, audits opposite end is pivotally connected to the said rod 33, which is attached by its lower end to said foot-treadle 31. To the lowerend of said shaft 44 is Asecured the blowiron-socket 32, into which the upper end of the blowiron 35 is placed, as shown in Figs. l and 13. To the upper end of the said hollow shaft 44 a fieXibie pipe 45 is suitably connected, which serves to convey air under pressure from any suitable source to said hollow shaft, and thence through an air-passage in said socket to the said blowiron and through the latter to molten glass gathered on the lower end thereof,

as usual,when said glass shall be introduced into the mold to be blown.

In Fig. l a blowiron is shown in connection with each mold in the positions occupied thereby when glass is being blown. Said blowirons are supported in proper posit-ion over the molds by two revoluble disks 56 and 57, Fig. l2, having corresponding semicircular recesses in their borders, two of which constitute an opening suitable for receiving a blowiron therein, as shown. One of said disks 56 has tooth-like*projections on its periphery, whereby the two disksV have a common revoluble movement when a blowiron is introduced therebetween. Said disks 56 and 57 are supported (two pairs for each blowiron) on two freely-revolving shafts 54 and 55, which shafts are in turn supported by suitable brackets 53, attached to the posts 52 and to the frame of the machine. A 'snapspring 84, secured by one end to the bracket 53, may be employed, if desired, for so regulating the rotary motion of the disks 56 -and 57 that the blowiron will more surely be brought centrally over the mold. The blowiron has an enlargement 58 thereon,whereby it is adapted to hang on said disks in proper operating position.

The operation of each mold and its accessories in blowing glass is as follows, it being understood that the shafts 6 and 7 are revolving: rlhe operator, having gathered molten glass on the blowiron, presses the foot-treadle 3l downward, thereby through rod and the described devices connected therewith causing the sections ofthe mold to move one away from the other, and thus open the mold,r and also lifting the shaft 44 and the blowironsocket 32, and the blowiron is then placed under said socket and the glass thereon between said mold parts, the blowiron hanging as shown in Fig. l. The said treadle is then released and the mold is then closed by the spring 64, and said socket drops onto the end of the blowiron. Air is now conveyed to the glass within the mold, expanding it in the usual manner. The lever 19 is now swung,carrying the clutch-collar into engagement with the clutch-sleeve 2l, whereby the table 63 and mold parts thereon are rotated in order to move the surface of the mold against the surface of the hot glass wi thin it and prevent any seam y appearance thereon; also,the mold-bottom is at the same time rotated by the described mechanism in a direction opposite to that of said mold, thereby smoothly finishing the bottom of the blown-glass article. The mold having received the desired number of turns or rotations, the pin 29 on the side of the ratchet-wheel 28 disengages the latch-spring 26 from the lever 19,1etting the spring 25 swing said lever and draw said clutch-collar out of engagement with the clutch-sleeve 2l, thereby stopping the revolution of the mold. The operator then again operates the treadie 3l and opens the mold and draws the socket 32 off from the blowiron. An attendant at the rear of the mold then removes the blowiron and the article thereon and the operator immediately dips the mold in the water in the tank 3 by mea us of said lever 37 and described connections between the same and the yoke-box 8 of the mold-supporting case 9, as shown in Fig.r5 in dotted lines, and the mold is then returned to operative position ready for a like successive operation. Should any water remain in the mold after having been brought to operative position again, as aforesaid, the mold may be opened for an instant, as before, when the mold will be sufficiently cleared of water and it will automatically close by its spring. As heretofore set forth, the mold is given a rotary movement while the glass article is being formed therein. Provision is also made, as stated, for rotating the blowiron by means of said hollow shaft 44 and driving means connecting the same with the main driving-shaft- 7. When it is desired to rotate IOO both the blowiron and the mold, their rotary motions will bc in opposite directions, whereby the surface of the article being blown will be moved with increasing rapidity against the surface of the mold. It' desired, the driving connections between said main drivingshaft and hollow blowiron-spindle may be disconnected, thereby stopping the rotation of the blowiron, but still leaving the mold to rotate, as aforesaid.

In this application l have shown a two-part sectional mold; but l desire to state that I am not the inventor of any variety of mold, and at the time of this invention I had never seen one used which had more lhan'two sections.
